We just did a minor bug fix to error code in the `amounts` module. This
change did not effect the public API but improved the display of two
error types from that module.
In preparation for doing a point release bump the version number and add
a changelog entry.
We have 2 crates that require an allocator, `bitcoin` and `base58ck` -
these crates should enable the "alloc" feature when depending on
`internals`.
For `units` we use the `internals::error::InputString` but do not enable
the "alloc" feature - this is a bug, it means that the parsed string is
being lost from the error types that use `InputString`.
Enable "alloc" for `bitcoin`, `base58ck`, and `units`.
- `bitcoin` and `base56ck` is just for good measure so we don't get
bitten later on.
- `units` is a bug fix and requires a point release.
In preparation for the initial release add a changelog. Note the version
number is already set to `v0.1.0` and this does not conflict with the
release currently on crates.io `v0.0.0`.
Make an attempt to improve the ergonomics and docs clarity of the
`units` crate.
- Don't inline error type re-exports, this keeps them up in the
"Re-exports" section and saves cluttering the other inlined docs.
- Re-export and inline the docs for `FeeRate` and `Weight` same as we do
for `Amount`. This makes the "Structs" section of the docs nice except
for the exclusion of the locktime types (which cannot be helped).
Move the `strip_hex_prefix` helper function to below where it is called.
Note that I was the original author of this helper so there is no excuse
for it being above - bad Tobin no biscuit.
This lint triggers when parsing a reference to a large struct as a
generic argument, which is wrong.
Allow it crate wide because [subjectively] this lint never warns for
anything useful.

Adds constructors to allow directly creating locktimes from time or
block counts; adds a flooring constructor to Time to match the ceiling
one; adds an explicit constructor to Height since the From<u16> was not
very discoverable.
Currently we are deriving the serde traits for the `absolute::{Height,
Time}` types, this is incorrect because we maintain an invariant on
the inner `u32` of both types that it is above or below the threshold.
Manually implement the serde traits and pass the deserialized `u32` to
`from_consensus` to maintain the invariant.
Close: #2559
When creating the ParseIntError in `hex_u32` I (Tobin) just cargo cult
programmed the generic stuff without thinking.
- The `is_signed` field is used to denote whether we were attempting to
parse a signed or unsigned integer, it should be `false`.
- The `bits` field should be directly set to 32.
d887423efc Enforce displaying Amount with trailing zeros (448 OG)
Pull request description:
It is common to display bitcoins using trailing zeros upto 8 decimals. This commit enforces:
- Displaying Amount in BTC with trailing zeroes by eight decimal places if a precision on the Amount is not specified.
- Displaying Amount in BTC upto the precision specified truncating the insignificant zeros.
- Displaying amount in BTC without any decimals if the remainder of the amount divided by the satoshis in 1 BTC is equal to zero using formula `satoshis.rem_euclid(Amount::ONE_BTC.to_sat()) != 0`
These are not breaking changes and all previous tests pass.
A testcase is added to for changes introduced.

cbee9781e8 Move unit types to units (Tobin C. Harding)
5bd0d7194b Remove unused absolute::Error (Tobin C. Harding)
Pull request description:
Move the following unit types to the new `units` crate:
- `locktime::absolute::{Height, Time}`
- `locktime::relative::{Height, Time}`
- `FeeRate`
- `Weight`
Also move the `parse` module as well as constants as required.
Do minimal changes to get things building:
- Feature gate on "alloc" as needed.
- Remove rustdocs that use `bitcoin` types.
- Re-export units types so this is a non-breaking change.
- Fix import paths.
Patch 1 was originally #2526, putting it in via this PR to try and speed up the process.

No clue how this got into master; found with `just sane`.

useless conversion to the same type: `amount::ParseAmountError`
As suggested, remove the useless conversion.

Sometimes people don't remember the exact number of decimal places
supported by denomination or don't want to count (e.g. when converting
fiat to BTC the calculator may yield too precise value). It's helpful to
say in error message at which digit the precision is too high.
This adds `TooPreciseError` struct containing the information and
improves the error message to display it.
This variant lacked pretty important information: what is the limit. We
could just write it in the error message but it's even better to move it
to a separate struct which also says how many characters exceed the
limit - this helps users know how many need to be deleted.
The `InvalidFormat` variant was pretty bad: it didn't make it clear what
exactly is wrong with the input string, especially since it was used
when the denomination was missing. Not only was this unhelpful to the
users who don't know they have to write the denomination when the amount
was otherwise correct but it was also attributed to a problem with the
amount rather than a problem with denomination.
To fix this the variant is replaced by `MissingDigitsError`,
`MissingError` and `InvalidCharError` - all the cases `InvalidFormat`
was originally used in.
`InvalidCharError` is effectively the same as the existing variant but
it was made into a separate error to enable special casing `.` and make
extensions possible. Further this opportunity was used to add a special
case for `-` as well.
`MissingDigitsError` currently contains special casing for empty string
and a string only containing minus sign. It's currently unclear if it's
useful so this change makes this distinction private and only makes it
affect error messages.
As opposed to the previous two variants, `MissingDenominationError` was
added to `ParseError`. The struct is currenly empty and may be extended
in the future with e.g. span information.
df1d2f6eb5 Add unchecked variants to Amount and SignedAmount (yancy)
Pull request description:
The checked variants have worse performance than the unchecked variants due to the additional branching operations. To improve performance where overflow is either not possible or not a concern, unchecked variants of `Amount` and `SignedAmount` are introduced for addition, subtraction and multiplication.
Note, it seems the default behavior for the test framework is to panic on overflow, so I haven't figured out a good way to add tests for this. Marking as a draft for now.

Previously the crate used negative reasoning to enable `std` which was
hard to understand, required the `prelude` module and wasn't really
needed because it's only needed when a crate wants to add `alloc`
feature-backwards compatibly and this crate always had the feature.
This cleans up usage to unconditionally use `#[no_std]` and then just
add `extern crate` on top as needed by activated features.
Using the crate without allocation was previously disabled making the
crate empty without the feature. This chage makes it more fine-grained:
it only disables string and float conversions which use allocator. We
could later provide float conversions by using a sufficiently-long
`ArrayString`.
